We recommend either our most favorable “WP Car Rental” theme, that is specially made for this plugin or “BeCarRental” design from “BeTheme” 250+ themes pack, which incorporates bunch of hi-end features (visual content editor, Google Fonts, Twitter Bootstrap etc.).
“BeTheme” uses their own icon set, so to have support for FontAwesome icons, you will also need to be sure that you enabled “Font Awesome” in Car Rental System Settings.
We recommend using “Full width” page template, but it can be any other great WordPress Premium theme, or any page template.
Also, make sure that you have set the “Steel Blue” style in Car Rental System Settings.
